If you've got a basic multivitamin in your medicine cabinet you already have the only supplement you need. Be advised that no "gainer supplement" including multivitamins are approved or proven by the FDA. That is why they must be labeled as supplements and not proven drugs or medication.
Not one is recommended by any medical, dietary, or regulatory organization.
They are overwhelmingly endorsed by the people making the money off them.
Most pre workouts contain some form of stimulant to accelerate heart rate. You can get the same effect from a few cups of coffee or any caffeinated drink.
Nobody needs a protein shake or pre workout stimulant.
We get all the protein we need from a complete diet of fresh whole foods from all food groups.
There is a small window of time immediately after intense weightlifting, not cardiovascular exercise, where the severely damaged lean muscle tissue can use (not demand) extra protein.
Marketers have taken advantage of this information and convinced consumers they NEED protein supplements to increase muscle size. And they are making a boat load of money selling the concept.
Along the same lines the body uses more calories to digest protein than fats or carbohydrates. The total however is insignificant. 30 additional calories from a 100 grams of protein per day diet.
Marketers have seized this information and convinced consumers that protein supplements cause weight loss. Again making a ton of money, So we ingest protein to build mass and reduce weight at the same time?
Try a lean meat or tuna sandwich on whole wheat an hour before exercise. Again after. A handful of raw nuts and a hard boiled egg. Any combination of lean protein and a complex carbohydrate to extend the absorption time. This gives the body a consistent supply of protein. Muscle repair, rest, and new tissue growth occur 24/7, not only right after exercise.
Spend your money at the grocery store instead of on unapproved supplements.
